Various apparatus and methods for bending a sheet of media are disclosed.

Sheet bending

Various embodiments and methods relating to a guide for pressing a medium towards a surface of a drum and for retracting the guide away from the surface are disclosed.

Medium pressing guide

Various embodiments and methods are disclosed for sheet ejecting in which a claw boost the twain positions and response to engagement of a cam follower with a cam and in which the cam follower is movable between a cam engaging position at a cam disengaging position.

Sheet ejecting

The present invention provides a printer having a platen, a chassis sidewall and an attachment portion connecting the platen to the chassis sidewall. The attachment portion biases the platen toward the chassis sidewall.

Printer chassis sidewall and platen assembly

In an inkjet printing apparatus an inkjet printhead has a plurality of inkjet nozzles which eject ink onto media located within a print-zone. A drive shaft is located upstream of the printhead and is incrementally rotated to advance the media. The drive shaft has a longitudinal axis, a first radius over a central length and a second radius less than the first radius at a first recess and a second recess, each said recess being peripheral to the central length. A plurality of pinch devices stabilize the media against the drive shaft. A first guide is aligned with the first recess and is spaced from an axis of the drive shaft by a first distance which is less than the first radius. A second guide is aligned with the second recess and is spaced from the axis by a second distance less than the first radius.

Controlling media curl in print-zone

In an inkjet printing apparatus an inkjet printhead ejects ink into a print-zone. A drive shaft, located upstream of the printhead, has a longitudinal axis, a first radius over a central length, and a second radius less than the first radius at a first recess and a second recess. Each recess is peripheral to the central length. A plurality of pinch devices stabilize the media against the drive shaft. A first guide and a second guide, spaced from the longitudinal axis, are aligned with and extend into the first recess and second recess.

An image transfer system, including a member for supporting print media, the member including a pair of sidewalls depending therefrom, a pair of end caps, wherein one end cap is connected to the sidewalls at an end thereof and the other end cap is connected to the opposite end of the sidewalls, and a heating element disposed against the underside of the member and in contact with each of sidewalls and end caps.
